Despite advancements in the treatment of individuals with Inflammatory Bowel Disease (IBD), many patients will require the need to utilize biological therapies during their disease course. Moreover, some patients with IBD develop disease manifestations outside of the GI (gastrointestinal) tract termed extraintestinal manifestations (EIM). We sought to establish an association between prior EIM exposure and the sequential use of biological therapies in patients with IBD. A retrospective analysis of 555 patients with confirmed IBD and relevant EIM data was performed. EIM exposure was treated as both a dichotomized (ever, never) variable and a categorical (0, 1, 2 or more) variable in our analysis. Crude ratios were established using logistic regression and multinomial regression models. Bivariate analysis was used to test for significant confounding variables and significant confounders were included in the final multivariate regression model. We found female sex (p < 0.001), a disease duration of 13 years or longer (p = 0.001), and an ileocolonic disease location (p = 0.036) to be significantly associated with EIM exposure. We found that a disease duration of 13 years or longer (p = 0.037), diagnosis of Crohn’s Disease (CD) (p < 0.001), corticosteroid use (p < 0.001), and an ileocolonic disease location (p = 0.021) to be significantly associated with use of biologics. Our final adjusted model did not show statistical significance, but did notably indicate that individuals exposed to 2 or more EIM had 1.51 times the odds of progressing to biological therapy (95%CI: 0.67, 3.41; p = 0.32) compared to those patients with no EIM history. As a result, EIM exposure may be an indicator for high-risk IBD patients likely to require biological therapy, especially among particular groups. Our data emphasizes the need for further studies to characterize the association between EIM exposure and specific EIM with the utilization of biologics.
